When you modify a file with the'A 'attribute set, its atime record does not change.

This can avoid some disk I / O processing in notebook systems. Files with the `a' attribute set can only be opened for writing in add mode.

Only superusers can set or clear this property. Files with the `c' attribute set are automatically compressed by the kernel on disk.

Uncompressed data is returned when reading from linux file properties.

A write to the file will compress the data before saving them to disk. Files with the `d' attribute cannot be backed up by running the dump (8) program. A file with the `i' attribute set cannot be modified: you can neither delete it nor rename it, you can't create a link to the file, and you can't write any data to it. Only superusers can set or clear this property. When you delete a file with the `s' attribute set, its data blocks are cleared and written back to disk.

When you modify a file with the `S' attribute set, the modification is synchronously written to disk, which has the same effect as the `Smount option applied to the file subsystem. When you delete a file with the `u' attribute set, its contents will be saved. This allows the user to request recovery of deleted files.
